Abstract
The utility model relates to a rear portion scraper plate conveyor machine tail of a working face, in particular to a driving and transmission device of a rear portion scraper plate conveyor machine tail. The device comprises a motor (1), a reducer (2) and a machine tail chain wheel shaft set (4), wherein the motor (1), the reducer (2) and the machine tail chain wheel shaft set (4) are sequentially in transmission connection, and the machine tail chain wheel shaft set (4) is installed on the machine tail (5). The device is characterized in that the motor (1), the reducer (2) and the machine tail (5) are substantially on the same line. By means of the driving and transmission device of the rear portion scraper plate conveyor machine tail, the problem that a supporting and protecting space at the rear portion of a transition support frame is occupied due to parallel arrangement of power portions of the rear portion scraper plate conveyor machine tail is solved, the transition support frame and a middle support frame can be designed to support frames in an uniform type, and technology procedures of frame increasing and frame decreasing conducted due to length change of the working face are simplified. Meanwhile, a coal drawing effect of an end head is improved, coal drawing capacity is improved, and recovery rate of coal resources is further improved. The center distance between a front portion scraper plate conveyor machine tail and the rear portion scraper plate conveyor machine tail and the center distance of the middle sections are consistent, a lag phenomenon of the rear portion scraper plate conveyor machine tail is reduced, and working conditions of the rear portion scraper plate conveyor machine tail are improved.
Description
Technical field
The utility model relates to work plane rear portion scraper conveyor tail, especially rear portion scraper conveyor tail drive transmission.
Background technology
Longwall Top Coal Caving Method, be one of important high-efficiency mining method of present China high seam mining of raw coal, in gentle dip, inclination, inclined thick and the medium-thickness seam of geological structure relative complex and condition relatively poor " three is soft ", " unstable " coal seam high-efficiency mining, have clear superiority.
As shown in Figure 1, the arrangement of existing fully mechanized coal face rear portion scraper conveyor tail power part is mainly and is arranged in parallel.Parallel arrangement exists many problems fully not solve at existing matching equipment, be mainly manifested in the following aspects: 1, scraper conveyor tail power part in rear portion is arranged in parallel, it is large to take the hydraulic support back space, cause the tail hydraulic support different from the middle frame structure, form special transition frame; 2, scraper conveyor tail power part in rear portion is arranged in parallel, and is subjected to the impact in tail-driving section position and space, and is crooked at drive end unit when causing rear portion drag conveyor actual arrangement operation, increased to a certain extent rear portion drag conveyor running resistance; 3, scraper conveyor tail power part in rear portion is arranged in parallel, and in advance of the face process, when face length changes, increases frame, subtracts frame process complexity, and workman's labour intensity is large, has simultaneously certain potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of rear portion scraper conveyor tail drive transmission, and the transition bracket rear portion support space that can reduce to take makes transition bracket and the middle bracket can interchange, simplifies the process that work plane increases frame, subtracts frame.
A kind of rear portion scraper conveyor tail drive transmission comprises motor, the reducer that is in transmission connection successively and is installed in tail sprocket shaft group on the tail that its special feature is: wherein motor, reducer and tail are substantially on same straight line.
Wherein reducer is in transmission connection by gear-box and tail sprocket shaft group.
After adopting the utility model, having solved rear portion scraper conveyor tail power part is arranged in parallel and takies the problem of transition bracket rear portion support space, make transition bracket and middle bracket can be designed to unified model support, simplified increasing frame, subtract the frame process because of the face length change.Improve simultaneously the termination drawing effectiveness, improve and put the coal ability, further improve coal recovery rate.The technical solution of the utility model makes front and rear part scraper conveyor tail center to center distance consistent with interlude center to center distance, reduces rear portion scraper conveyor tail hysteresis, improves the operation condition of rear portion scraper conveyor tail, improves the Whole Equipment operational reliability.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model background technology;
Accompanying drawing 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, the utility model is a kind of rear portion scraper conveyor tail drive transmission, comprise motor 1, the reducer 2 that is in transmission connection successively and be installed in tail sprocket shaft group 4 on the tail 5, and intermediate channel 6, wherein on same straight line, reducer 2 is in transmission connection by gear-box 3 and tail sprocket shaft group 4 substantially for motor 1, reducer 2 and tail 5.
The utility model is by changing the transfer mode of power, the gear-box 3 that the design equivalence is transmitted between tail sprocket shaft group 4 and reducer 2 carries out transmission of power, make whole power part and rear portion conveyer integral body become " yi word pattern " to arrange, and " yi word pattern " arranges the motor 1, reducer 2, sprocket shaft group etc. that can share same model with former " being arranged in parallel ", reduced the kind of same model product.
The utility model has been realized comprehensive extracting and caving face rear portion scraper conveyor tail 5 power parts (drive transmission) " yi word pattern " layout, reduce to greatest extent the height at tail sprocket shaft group 4 centers, so that milder along radian on the tail 5, realize reducing the upper upper purpose along application life that increases along wearing and tearing.Improve simultaneously the termination drawing effectiveness, improve and put the coal ability, further improve coal recovery rate.Make scraper conveyor tail 5 center to center distance in front and rear part consistent with interlude center to center distance, reduce rear portion scraper conveyor tail 5 hysteresis, improve the operation condition of rear portion scraper conveyor tail 5, improve the Whole Equipment operational reliability.
Claims (2)
1. rear portion scraper conveyor tail drive transmission, comprise motor (1), the reducer (2) that is in transmission connection successively and be installed in tail sprocket shaft group (4) on the tail (5), it is characterized in that: wherein motor (1), reducer (2) and tail (5) are substantially on same straight line.
2. rear portion as claimed in claim 1 scraper conveyor tail drive transmission, it is characterized in that: wherein reducer (2) is in transmission connection by gear-box (3) and tail sprocket shaft group (4).
